Probabilistic matrix factorization is a classic algorithm for recommender systems. However, both the rating matrix and trust matrix become sparser, which makes the recommended results inaccurate. We propose a hybrid method based on probabilistic matrix factorization and directed trust. First, we apply ...
In this paper wepresent the Probabilistic Matrix Factorization (PMF) model which scales linearlywith the number of observations and, more importantly, performs well on thelarge, sparse, and very imbalanced Netflix dataset. We further extend the PMFmodel to include an adaptive prior on the model ...
The proposed algorithm, which is a variation of a well known algorithm, uses the fact that TDMs are normally rectangular sparse matrices to reduce the computation time and also to achieve better accuracy than the original algorithm. In addition, all matrix products in the proposed algorithm are ...
Based on this, we propose an innovative framework named CDPMF-DDA, which utilizes probabilistic matrix factorization to construct multi-view contrastive learning, deeply exploring potential drug-disease associations. By conducting contrastive learning across different views, the method effectively captures the...
Inferring gene regulatory networks (GRNs) from single-cell data is challenging due to heuristic limitations. Existing methods also lack estimates of uncertainty. Here we present Probabilistic Matrix Factorization for Gene Regulatory Network Inference (PM
The implementation in this repo is described in: "Distributed Matrix Factorization using Asynchrounous Communication", Tom Vander Aa, Imen Chakroun, Tom Haber, https://arxiv.org/pdf/1705.10633 Input is in the form of a sparse matrix of values (e.g. movie ratings) R. The outputs are two...
Stacking all data matrices recorded during pathogenesis into a single matrix resulted in a data matrix with approximately 10 million columns or about 2 billion matrix entries (encoding the reflected energy at different spectral bands). Before determining the topics, we first created sparse matrices ...
Gao et al. proposed a method of predicting miRNA–disease associations based on “dual network sparse graph regularized matrix factorization” (DNSGRMF) [49]. In this method, the L2,1-norm was used to make up for the sparsity in unknown associations. They presented effective “nearest profile...
